> and if there was a way for my washing machine to have a 3h window overnight to run in to be done for 7:30 I'd do it in a heartbeat.

I think most of these appliances sold today have at least some sort of "delay start" function. We use that to do exactly what you describe. Not even for nght tariff, it's just convenient to time it like that.

Every washer, even basic ones, I've owned that were made post-2000 had a delay start function. Even my most basic one that just had dials to select options, it had a 2/4/6/8-hour delay dial. I figured it was a common feature by now.

		A 2-hour granularity delay start would drive me insane. Better than nothing though. And maybe the dial one works with a timer on the outlet too, as the program is mechanically selected.
